Magnesium for Kids: Citrate vs. Glycinate – Which one does your child actually need?

I see a lot of parents asking about magnesium lately. It’s an absolute powerhouse mineral involved in over 300 enzymatic processes in growing bodies, but standing in the supplement aisle can be completely overwhelming.

If you're stuck deciding between Magnesium Citrate and Magnesium Glycinate, here is the quick breakdown of what each one actually does.

TL;DR: Choose Citrate for constipation and digestion. Choose Glycinate for better sleep, calming, and nervous system support.

Magnesium Citrate (The Digestion Helper)

Think of Citrate as the "plumber." It pulls water into the intestines, which makes it highly effective as a gentle, natural laxative.

• Best for: Kids who struggle with regular bowel movements or chronic constipation.
• Things to note: Because it gets things moving, too high of a dose can cause loose stools or an upset stomach. Start low!

Magnesium Glycinate (The Calming Mineral)

Think of Glycinate as the "chill pill." In this form, magnesium is bound to the amino acid glycine, which allows it to cross the blood-brain barrier easily without upsetting the stomach.

• Best for: Kids who struggle to wind down at night, experience growing pains, or need support with anxiety, mood regulation, and focus (often discussed in ADHD management).
• Things to note: It is highly bioavailable (easily absorbed by the body) and the least likely form to cause diarrhea

Food is always the best first step (spinach, pumpkin seeds, bananas, oats, and even dark chocolate/cacao are great sources). But when food falls short, a targeted supplement can make a huge difference in how your child feels and sleeps.
